On September 7, Healing Paper announced through a public notice that on September 4, there was abnormal access to the integration feature (API) used to view consultation records, resulting in a leak of some customer personal information.

Healing Paper explained that after detecting suspicious activity, they blocked the affected access route, but confirmed that the same attacker attempted to access the system again through a different route on September 5.

According to Healing Paper, the number of individuals whose information was leaked totals 219,665. Of these, about 160,000 users are from Korea, 48,000 from Japan, and 4,218 from Taiwan.

The leaked items include names, phone numbers, email addresses, dates of birth, gender, country or region of residence, social network service (SNS) login IDs, and information on user devices.

Additionally, items requested during consultations—such as event names, procedure names, doctor names, hospital names, and visitor names—were also included in the leaked information.

Healing Paper stated that it notified affected users individually and enabled them to check which information had been leaked through the Gangnam Unni website for 30 days. The company also cautioned, "Please be especially careful if you receive contact from someone impersonating Gangnam Unni or a hospital, offering guidance or discounts, or attempting to induce you to click a link."
